LTC1151CSW#PBF

LTC1151 is a high voltage, high performance dual zero-drift operational amplifier. The two sample-and-hold capacitors per amplifier required externally by other chopper amplifiers are integrated on-chip. It also incorporates proprietary high voltage CMOS structures which allow operation at upto 36V total supply voltage. It has a typical offset voltage of 0.5µV, drift of 0.01µV/°C, 0.1Hz to 10Hz input noise voltage of 1.5µVP-P, and a typical voltage gain of 140dB. It has a slew rate of 3V/µs and a gain-bandwidth product of 2.5MHz with a supply current of 0.9mA per amplifier. Overload recovery times from positive and negative saturation are 3ms and 20ms, respectively. It is used in applications such as strain gauge amplifiers, instrumentation amplifiers, electronic scales, medical instrumentation, thermocouple amplifiers, high resolution data acquisition.
